Answer:
19.209372712298546 (C)
Step-by-step explanation:
For this you use pythagorean theorem. a squared + b squared = c squared which is your missing side. 15 squared is 225 and 12 squared is 144 so together thats 369. Now we know c squared is 369 so we find the square root of that and boom. So your answer is C (19.2)
y = -4x + 3 this line has slope = -4
parallel lines, slope is the same so slope of new line is also equal -4
passing thru (8, -3)
y = mx + b
b = y - mx
b = -3 - (-4)(8)
b = -3 + 32
b = 29
equation:
y = -4x + 29
hope it helps
5x-22=3x+10
2x-22=10
2x=32
X=16
Answer:
Ray = 19 yrs old
Tom = 25 yrs old
John = 57 yrs old
Explanation:
Let x be the years of Tom
R = x - 6
J = 3R = 3(x - 6)
T = x
R + J + T = 101
x - 6 + 3(x - 6) + x = 101
2x - 6 + 3x - 18 = 101
5x - 24 = 101
5x = 125
x = 125/5 = 25
R = 25 - 6 = 19
J = 3(25 - 6) = 57
T = 25
